Problems solved by technology

[0002] In the general operation process, a double "J"-shaped ureteral stent is usually inserted into the human ureter. After a period of time, the ureteral stent needs to be taken out. The common way to take the tube is to enter the urethra through a cystoscope. Then use grasping forceps to grasp the ureteral stent tube, which has the disadvantages of inconvenient operation, low operation efficiency and high operation risk

Abstract

The invention relates to a pulling-out device for a urine conveying support pipe. The pulling-out device comprises a hollow sleeve and a rigid connecting wire for hanging and taking the urine conveying support pipe. An opening is formed in one end of the sleeve; a first through hole and a second through hole are formed in one end, far away from the opening, of the sleeve; the first through hole and the second through hole are formed at intervals; the connecting wire comprises a main body part and two free ends arranged at the two ends of the main body part. The two free ends respectively penetrate into the sleeve from the first through hole and the second through hole and penetrate out of the opening; the two free ends move in the direction close to the first through hole and the second through hole, and the end, away from the free ends, of the main body part arches towards the outer side wall of the sleeve to form a sleeving part for hanging and taking the urine conveying support pipe. The pulling-out device for the urine conveying support pipe has the advantages of being simple in structure, low in manufacturing cost, easy and convenient to operate, high in operation efficiency and low in operation risk.

Description

technical field [0001] The invention relates to a medical device, more specifically, to a pull-out device for a ureteral stent. Background technique [0002] In the general operation process, a double "J"-shaped ureteral stent is usually inserted into the human ureter. After a period of time, the ureteral stent needs to be taken out. The common way to take the tube is to enter the urethra through a cystoscope. Then the ureteral stent is grasped by grasping forceps. This method has the disadvantages of inconvenient operation, low operation efficiency and high operation risk. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved pulling device for ureteral stent tubes. [0004] The technical solution adopted by the present invention to solve the technical problem is: to construct a pull-out device for a ureteral stent, including a hollow sleeve and a rigid connecting wire for hanging the ureteral stent; [...
